All Headlines
Popular sugar substitute linked to brain damage and stroke risk
A widely used sugar substitute found in everything from keto snacks to diet drinks may not be as harmless as it seems. New research shows that erythritol can disrupt brain blood vessel cells, reducing their ability to relax, increasing harmful oxidative stress, and impairing the body’s ability to break down clots. These changes create conditions that could raise stroke risk, even at typical consumption levels.
After 20 years, scientists finally explain the Crab Pulsar’s strange “zebra stripes”
For decades, astronomers have been puzzled by strange “zebra stripe” patterns in radio waves from the Crab Pulsar — bright bands separated by complete darkness. Now, new research suggests the answer lies in a cosmic tug-of-war between gravity and plasma. The pulsar’s plasma spreads light apart, while gravity bends it back together, creating interference patterns that form the striking stripes.
This quantum computing breakthrough may not be what it seemed
A team of physicists set out to test some of the most exciting claims in quantum computing—and found a very different story. Instead of confirming breakthroughs, their careful replication studies revealed that signals once hailed as major advances could actually be explained in simpler ways. Despite the importance of these findings, their work initially struggled to get published, highlighting a deeper issue in science.
This new therapy turns off pain without opioids or addiction
Scientists have developed a new gene therapy that quiets pain at its source in the brain—without the addictive risks of opioids. Using AI to map how pain is processed, they created a targeted “off switch” that mimics morphine’s benefits but skips its dangerous side effects. In early tests, it delivered lasting relief without affecting normal sensations. The discovery could mark a major step toward safer, non-addictive pain treatments.
Stroke triggers a hidden brain change that looks like rejuvenation
After a stroke, the brain may do something surprisingly hopeful—it can “refresh” parts of itself. Researchers analyzing brain scans from over 500 stroke survivors found that while the damaged side of the brain appears to age faster, the opposite, unaffected side can actually look younger. This unexpected shift seems to reflect the brain’s effort to rewire itself, strengthening healthy regions to compensate for lost function.
New cholesterol guidelines could change when you get tested
A major new U.S. cholesterol guideline is shifting the focus toward earlier, more personalized prevention of heart disease. It urges people to start screening sooner—sometimes even in childhood—and highlights the importance of tracking not just LDL (“bad”) cholesterol but also genetic risk factors like lipoprotein(a). A new, more advanced risk calculator now uses broader health data to better predict heart attack and stroke risk over decades.
Scientists say the evidence is clear: E-cigarettes beat patches and gum in helping smokers quit
Nicotine e-cigarettes may be one of the most effective tools yet for quitting smoking, according to a sweeping review of global research. By analyzing findings from 14 major reviews spanning nearly a decade, researchers found consistent, high-quality evidence showing that nicotine vapes outperform traditional methods like patches, gum, and even behavioral support. While some lower-quality studies produced mixed results, the strongest data clearly favored nicotine e-cigarettes.
This hidden state of water could explain why life exists
Scientists have finally found a hidden “critical point” in supercooled water that explains why it behaves so strangely. At this point, two different liquid forms of water merge, triggering powerful fluctuations that affect water even at normal temperatures. The breakthrough was made possible by ultra-fast X-ray lasers that captured water before it froze. This discovery could reshape our understanding of water’s role in nature—and possibly even life itself.
This new carbon material could make carbon capture far more affordable
Scientists have created a new kind of carbon material that could make carbon capture much cheaper and more efficient. By carefully controlling how nitrogen atoms are arranged, they found certain structures capture CO2 better and release it using far less heat. One version works at temperatures below 60 °C, meaning it could run on waste heat instead of costly energy. The discovery offers a powerful new blueprint for next-generation climate technology.
Scientists discover why your appetite suddenly disappears when you’re sick
Scientists have uncovered how your body actually tells your brain to stop eating when you’re sick. In a new study, researchers found that specialized cells in the gut detect parasites and send signals that ultimately trigger the brain to suppress appetite. This process builds over time, explaining why you may feel fine at first but then suddenly lose interest in food as an infection takes hold.
Scientists discover a hidden system that turns brown fat into a calorie burner
Scientists have identified a key biological system that helps brown fat burn energy by building the networks it needs to function. A protein called SLIT3 splits into two parts, with each piece guiding the growth of blood vessels and nerves inside brown fat. These structures allow the tissue to pull in nutrients and rapidly convert them into heat instead of storing them as fat.
Scientists say we’ve been looking in the wrong place for human origins
A fossil ape discovered in northern Egypt is reshaping the story of human evolution. The species, Masripithecus, lived about 17 to 18 million years ago and may sit very close to the ancestor of all modern apes. This finding challenges the long-standing focus on East Africa. Instead, it points to northern Africa and nearby regions as a possible birthplace of apes.
